Abstract
A method of fabrication of an emergency shelter to be used under the floor of a residential or commercial structure. In the preferred embodiment, a prefabricated acrylic shelter is sized to accommodate at least one individual in a crouching or sitting position. The shelter is placed prior to the pouring of a slab foundation or the building of the floor in a pier and beam foundation. The shelter is preferably fabricated by vacuum forming a top sheet and a bottom sheet of ⅛ inch acrylic sheet on molds to form top and bottom sections which are then sprayed with an epoxy-fiberglass composition for reinforcement.
Claims8
A method of manufacturing a fiberglass-reinforced emergency storm shelter unit, the shelter having an upper section and a lower section, the method comprising the steps of:
- preparing a vacuum-forming mold for the upper section;
- heating a first acrylic sheet;
- vacuum-forming the first heated acrylic sheet to the upper section mold, thereby forming a shell for the upper section;
- applying approximately ¼″ thickness of fiberglass and epoxy resin reinforcement to the back of the upper section shell, thereby forming the upper section;
- preparing a vacuum-forming mold for the lower section;
- heating a second acrylic sheet;
- vacuum-forming the second heated acrylic sheet to the lower section mold, thereby forming a shell for the lower section;
- applying approximately ¼″ thickness of fiberglass and epoxy resin reinforcement to the back of the lower section shell, thereby forming the lower section;
- and
- attaching the lower section to the upper section, thereby forming the shelter unit.
